4 Days Ceph In-Depth Remote/Online Training

CEPH, OPEN SOURCE SCALE-OUT STORAGE

Ceph is a high-performance, open-source storage solution that scales to fit almost any use case: virtual servers, cloud, backup, and more. It's powerful, but getting it right takes more than reading the docs. Sessions are kept small, the focus stays hands-on, and the agenda can be tailored to your team's needs.

This training gives you the practical knowledge to plan, deploy, and operate Ceph with confidence.

OFFICIAL CEPH TRAINING BY CEPH FOUNDATION MEMBERS

croit is a Ceph Foundation Founding Member providing instructor-led Ceph training worldwide. Since 2017, we have helped organizations deploy, operate and scale production Ceph clusters. The course is taught by engineers who work with Ceph every day and covers architecture, deployment, operations, troubleshooting, performance tuning, CephFS, RBD, RGW/S3 and production best practices for enterprises and service providers.

TRAINER

Our trainers bring practical experience from real production Ceph environments, including deployment, operations, troubleshooting and 24/7 support. The sessions stay hands-on, with time for technical questions, architecture discussions and examples from real customer projects.

MATERIALS PROVIDED

• Digital documentation

• Virtual training center

• Certificate of completion

TARGET GROUP

This course is for IT administrators responsible for keeping storage environments running 24/7. Whether you work closely with developers, support end users, or run your own storage applications, basic Linux knowledge is all you need to get started.

TECHNICAL REQUIREMENTS

• A stable, high-speed internet connection (we recommend at least 25 Mbit/s downstream and 5 Mbit/s upstream).

• A computer capable of running a modern web browser for lab access.

• A headset, or a microphone with speakers, for active participation in discussions and Q&A.

• A webcam is recommended to support a more personal and interactive workshop atmosphere.
